[gnome-shell/wip/fmuellner/replace-app-menu: 10/10] panel: Restrict app menu width

[Florian Müllner <fmuellner src gnome org>]

commit 605c7b3d4b62523e7dee3bfa597acb7543d90078

    panel: Restrict app menu width
    
    Window titles aren't restricted in length, so the menu may end up unwieldily
    width. Commit 0bec76b6ee therefore limited the app context menus, but that
    got accidentally dropped in commit 0ded0dbfd5. Add back the limitation and
    extend it to the new app menu as well.
